Plants and photosynthetic algae and bacteria use energy from sunlight to combine carbon dioxide (C02) from the atmosphere with water (H2O) to form carbohydrates. These carbohydrates store energy. Oxygen (O2) is a byproduct that is released into the atmosphere. This process is known as photosynthesis.
The lost electrons in photosystm II are replaced by splitting water molecule into oxygen, hydrogen ions, and electrons. 9. What is the role of water in the photosynthetic process? Water splits into oxygen, hydrogen ions, and electrons to replace the lost electrons of photosystem II in light-dependent reaction. Also, as hydrogen ions pass through ATP synthase, ATP is formed to use in the light-independent reaction.
